This one is simple.
A girl in HS wants to be popular. So she lets guys feel her up. It turns her on a lot and when one guy presses her just a little, she willingly goes down on him. Her first taste of cum opens her up to a whole new level. To her, it is the best tasting thing she has ever tasted. And she wants more.
This leads from feeling-up/making out sessions turning into oral sex. Inevitably, she soon loses her virginity. And now she really craves cum - in her or on her, it doesn't matter. She soon becomes known as the High School Cum Queen, willing to swallow a load from anyone and everyone. Teachers get involved, the football team, the Geek Club, everyone. And she loves every minute of it.
As she progresses through HS, and goes to parties, she soon realizes she could make money. She's soon masquerading as a stripper for parties, more then willing to go that extra mile to free that load from her clients, no matter how old they are. By the time she is 18, she is well known for doing just about anything with anyone.
Instead of going to college, an agent from the Porn Industry comes knocking on her door. She doesn't need to try very hard to convince him she has what it takes and she is soon staring in movies, rewarded not with just money, but with the cum she so desperately craves.
[Raunchy, yes, smutty, yes. Looking for a HS Cum Queen. Story will progress from early age to her peak years.]
